SI3460
Overview
The Si3460 is a single-port -48 V power management controller for IEEE 802.3af-compliant Power Sourcing Equipment (PSE). Designed to minimize system cost and ease of implementation in embedded PSE endpoint (switches) or midspan (power injector) applications, the Si3460 operates directly from a 12 or 15 V input supply and integrates a digital PWM-based dc-dc converter for generating the -48 V PSE output supply.
